Wriggle \Wrig"gle\, v. i. [imp. & p. p. {Wriggled}; p. pr. & vb.
n. {Wriggling}.] [Freq. of wrig, probably from OE. wrikken to
move to and fro; cf. LG. wriggeln, D. wrikken, Sw. vricka,
Dan. vrikke.]
To move the body to and fro with short, writhing motions,
like a worm; to squirm; to twist uneasily or quickly about.
Both he and successors would often wriggle in their
seats, as long as the cushion lasted. --Swift.
